Was playing EA last night one last time before my brother left out of town, and I would notice my polymorph abilities would sometimes fail to trigger correctly.
The combat chat log would say something like, "used Skin Graft" but all my cooldowns would still be active, and my armor still in place.
Same with Chameleon Cloak and Heart of Steel. They would trigger the AP cost, chat log the spell, complete the animation cycle, but not take effect.
Those are the 3 abilities I've noticed, I am not sure if there are more. I also know that polymorph alongside summoning were release much more recently compared to the others so perhaps the bugs are worked out in the final release. I am just curious if anyone else has observed this issue?
